摘要：
Illuminated ophthalmic microsurgical instrument, comprising: a microsurgical instrument (48, 50, 51) having a distal tip； and an optical fiber (56) for supplying a beam of light to a surgical site in one eye, the optical fiber including a proximal end (60) for receiving a beam of light (70) from a light source (72), and a distal end (66) near the distal tip of the microsurgical instrument for emitting the light beam, and the distal end includes a bevelled end face (82) oriented toward the distal tip (76) of the microsurgical instrument, at an oblique angle with with respect to an optical axis of the optical fiber (56), characterized in that the refractive index of the optical fiber is greater than an index of refraction of a vitreous region of the eye such that an angle of propagation of the light beam with with respect to the bevelled end face (82) is greater within the vitreous region than within the optical fiber, causing an angular distribution of the beam of light emitted away from the optical axis of the optical fiber and away from the microsurgical instrument, when using this Te to perform an ophthalmic surgical intervention.Instrumento microquirúrgico oftálmico iluminado, que comprende: un instrumento microquirúrgico (48, 50, 51) que tiene una punta distal； y una fibra óptica (56) para suministrar un haz de luz a un sitio quirúrgico en un ojo, incluyendo la fibra óptica un extremo proximal (60) para recibir un haz de luz (70) desde una fuente de luz (72), y un extremo distal (66) próximo a la punta distal del instrumento microquirúrgico para emitir el haz de luz, y el extremo distal incluye una cara extrema biselada (82) orientada hacia la punta distal (76) del instrumento microquirúrgico, en un ángulo oblicuo con respecto a un eje óptico de la fibra óptica (56), caracterizado por que el índice de refracción de la fibra óptica es mayor que un índice de refracción de una región vítrea del ojo de tal manera que un ángulo de propagación del haz de luz con respe
